The mechanical fences can be modular welded mesh systems which can be easily installed by anyone however due to their inflexibility, their real value is quite low. The more reassuring choice is a strained wire mesh mechanical fence system which can be made with the traditional V-mesh featuring 2 twisted horizontal cables and vertical wires wrapped around each horizontal cable. However based on experience, the TORNADO TITAN mesh provides outstanding quality and flexibility with its anti-slip knots. Horizontal stay wires are joined to the vertical line wire with an innovative secure non-slip knot of a different material. This technology would even allow for an 8-meter post spacing but for a fence system to really operate safely in the long term, 5-6-meter post spacing should be applied. During installation it is recommended to use a hydraulic post driver to drive the (preferably) acacia pointed posts into the ground without preliminary drilling.
